What factors can lead to Patella Dislocation?
• Weak VMO – The VMO ( vastus medialis obliquus) is used to keep the patella on track in the patellofemoral groove during knee movements by pulling it towards the middle of the knee joint- an action known as ‘tracking’. Poor orientation of the muscle fibres or weakness in the muscle will leave the patella far more susceptible to dislocation. • Pronation of the feet. • Q-angle – Some people have a larger than normal femoral angle (known as the Q-angle) and may have a ‘knock-kneed’ appearance (genu valgum). When the person straightens their leg, the patella will be forced to the outside of the knee. Thus any extra force applied to the inside of the knee may result in patellar dislocation. Symptoms of Patella Dislocation: • The knee may be swollen • The patella will be painful • Reduced mobility in the knee • Obvious displacement of the knee cap How can the athlete treat this injury? • Cold therapy and rest (R.I.C.E.) • Immediately see a medical professional • Use of a support or heat ret
